Thanks, there are a lot good sister suggestions and many I wasn't aware of.

As, it stands now It looks like most would make the cut-off for notability using the current criteria. I was looking for the less credentialed of the sisters to have at least twenty-five screen credits, identifiable viewer recognition, as well as, a lead or prominent role on a hit movie or hit TV series. A few sister groups fit the honorable mention category due to a well know actress whose sister(s) has only a handful of acting credits and a substantially lower profile(s). I will have to rework to cull the list or split into two. As I now have forty viable answers with solid sister credentialed combos and forty more well known options with a weaker actress sister in the combo.

Thanks, I made the corrections. As for the Fishers, the connection I am trying to make is a maternal one that may not be obvious or known to all.

Although, it shouldn't be a leap to make the connection Eddie Fisher's
daughters are named Fisher or Richard Mill's daughters are named Mills. I
thought not all poll-takers would know that these talented sisters were
born into the business, in large part due to their mothers, especially
when they have different last names. I used the notations for Gummer Sisters (Meryl Streep's daughters), RichardsonSisters (Vanessa Redgrave's daughters), Thompson Sisters (Phyllida Law's daughters), and Fisher Sisters (Debbie Reynolds's daughter and step-daughters).

My goal is to be clearer, but not to over-complicate the issue. There are a quite a few issues with sisters having different names that I am trying to clarify. They include remarriages, half-sisters with different parents, stage names as well as using their mother's maiden names professionally.

As for the Kardarsian-Jenner Sisters being actresses I had the same reservations. But with the prominence of reality TV, blurring the line of how much is real and how much scripted, I think an argument could be made. I won't include it as a regular option, but I thought using it as a placeholder for Another Not Listed or Honorable Mention Sisterly Group would be a good idea, since the votes should be for all the other options anyways.
